1 Claim.

This invention relates to signal lights and may be called an "alternation gleam light; an oba light of this character which is comparatively simple in construction, can be used for various purposes, and is otherwise well-designed for the purpose intended.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawing wherein- Figure 1 is a longitudinal sectional view throught the light.

Figure 2 is a longitudinal sectional view through the light taken substantially on the line 2-2 of Figure 1, and

Figure 3 is a transverse sectional view through the light taken substantially on the line 3-3 of Figure 1.

Referring more in detail to the drawing it will be seen that the improved light comprises an elongated tubular casing 5 that at one end is equipped with a magnifying lens 6 secured in position on the casing through the medium of a retaining frame I.

For the opposite end of the casing 5 there is provided a flanged cap 8 equipped on the inner side thereof with a bracket 9 that serves to support within said end of the casing 5 a reflector II) of substantially frusto-conical shape and which is positioned within the casing 5 immediately behind an incandescent bulb II. To accommodate the bulb I I the casing 5 has suitably mounted interiorly thereof an electric lamp socket I2 from which extends a suitable lamp cord I3 whereby the socket may be placed in any suitable electric circuit.

. Further in accordance with the present invention there are positioned within the casing 5 intermediate the bulb II and the lens 6 obstructors or ray diffusers I4 and I5, respectively.

Each of the obstructors or diffusers I4 and I5 embodies an annular frame I6 which at one side is provided with an inturned flange to which are suitably secured in any suitable manner the respective opposite ends of relatively spaced strips I1 of suitable material.

The strips I! of the diffuser or obstructor l4 are staggered in relation to the strips ll of the obstructor or diffuser I5 so that the light rays will be filtered through the obstructors in the manner suggested in Figure 2 to the end that the light when illuminated will appear to be flashing, that is to say will appear to be rapidly alternately blinking as one approaches the light.

This flashing may be increased or diminished by adjusting the diffuser or obstructor I4 longitudinally within the casing intermediate the diffuser I5 and the magnifying lens 6; the frame I6 of the diffuser I4 having extending from diametrically opposite sides thereof screws or the like l8 that are accommodated in slots I9 provided in diametrically opposite sides of the casing 5 as shown in Figure 1.

The screws I8 serve to secure to the frame of the diffuser I4 narrow elongated strips 20 that are disposed opposite the slots I9 and serve as closures therefor. I

The diffuser or obstructor I4 is, of course, adjusted relative to the diffuser or obstructor I5 by readily shifting the diffuser I4 to the position of adjustment, and by such an adjustment the desired magnifying of the strips I! by the lens 6 is produced.

A light embodying the features of the present invention will be found to serve admirably for attracting and holding attention and may therefore be used as a signal lamp, or for any other purpose found desirable.

It is thought that a clear understanding of the construction, operation, utility and advantages of a lamp of this character will be had without a more detailed description; it being noted that if desired the casing 5 of the lamp may be pivoted, or otherwise secured at diametrically opposite sides thereof, and as at 2|, to the converging ends of bracket arms 22 extending from any suitable support. Thus the casing may be swung on the pivots 2I as may be found desirable in using the lamp as a signal lamp.

It is also to be understood that While I have herein shown and described a preferred embodiment of the invention, it is in no wise intended to restrict the invention to the precise details of construction, combination and arrangement of elements as so illustrated and described, other than as may be required by the prior art and scope of the appended claim.

Having thus described the invention what is claimed as new is:
